What should I pay attention to when using Hot melt adhesive?

       Hot melt adhesive is an adhesive with strong plasticity. It has strong initial viscosity and a general odor of light rosin resin. It has a wide bonding range and can be bonded to many materials. So easy to use Hot melt adhesive has What should be paid attention to?

       First of all, it is necessary to select a suitable hot-melt adhesive according to the application requirements, process parameters, temperature, pressure and glue consumption. The amount of glue used is more suitable. Too much usage is waste. Too little usage will result in extremely low adhesion and may lead to aging quality risks.

       When changing to other materials, it is necessary to re-measure the adhesive performance and aging rate of the adhesive. In order to keep the plastic box clean, you need to cover the plastic box immediately after adding the glue. In addition, you need to be careful not to put packaging materials such as release paper into the plastic box.

       The hot melt adhesive in the workshop needs to be tightly sealed and tightly packed to prevent dust from entering. There is also a need to regularly check the position of the glue in the plastic tank. Generally speaking, it is necessary to keep the liquid level above 75% of the volume of the plastic tank. Enough for one shift.

       If the production line is temporarily shut down for more than 2 hours, it is necessary to lower the operating temperature of the Hot melt adhesive machine by 20-30 ° C, and then adjust the temperature back to the set value during operation. In the after-sales in winter, the operating temperature of the melter can be appropriately increased by 10-20 ° C, so as to reduce the environmental temperature change and the effect on the bonding effect.
